' PAPER CONTAINER Filed Feb. 1, 1944 giras Patented May 29, 1945 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to paper containers, and

has more particular reference to containers of this kind embodying a long strip-like container element, having a series of pockets adapted for reception of precision parts, and adapted to bev rolled into a compact bundle containing a given or predetermined number of such parts.

More particularly, the present invention relates to a container of the above kind which may be made of a single strip of paper in any desired length to contain any desired number of pockets, and wherein an integral closure flap is provided for closing all of the pockets and insuring effective protection of the precision parts, one of each is placed in each pocket.

The primary object of the present invention is to provide an improved container of the above kind in which the pockets are defined or formed by machine stitching folded portions of a paper vstrip together along spaced parallel lines, the

stitching including interlocked bottom or bobbin and top or spool threads, the threads being looped one about the other aty the terminus of each line of sitching aty the bottoms of the pockets, and being extended diagonally from each such terminus to the start of .the next line of stitching in non-interlocked relation across the pockets to reinforce Ithe latter and permit speedy production of the containers without repeated cutting of the threads and starting anew on each line of stitch- The present invention will be readily understood .from the following description when considered in connection with the accompanying drawing, in which:

Figure 1 is a fragmentary elevational view of a container, embodying the present invention, in partly rolled condition, the unrolled portion being in front elevation.

Figure 2 is an enlarged fragmentary view showing a few of the pockets in rear elevation.

Figure 3 is a section on line 3--3 of Figure 2;

and

Figure 4 is a fragmentary plan view of the paper strip from which .the container is made.

Referring in detail to the drawing, the present container is made from a strip of paper 5, preferably two-'ply anti-corrosive crepe paper. This paper strip may be of any desired length, depending upon the number and width of the pockets.

strip is folded along a longitudinal line a to provide front and back portions 6 and 1, respectively, and a closure ap portion 8. projecting above the portions 6 and l. The folded portions 6 and 1 are then machine stitched together along spaced parallel lines transversely of .the strip, as at 9, the stitching embodying a bottom or back bobbin thread I and a top or front spool thread II interlocked as at I2 as is commonwith machine stitching. Thus, between each pair'of adjacent lines of stitching a pocket I3 isformed, and the pockets may be closed by folding the closure flap portion 8 on the lineb onto thev front n portion 1 as-shown by dotted lines in Figure 3. In accordance with the present invention, the threads l0 and II are looped one about the other at the bottom .terminus of each line of stitching, as at I4, and the threads are then extended diagonally from each bottom terminus to the top or start of the next line of stitching, as shown. The diagonally extending thread portions are noninterlocked and respectively extend across the back and front of each pocket to reinforce the latter. At the same time the stitching operation is continuous in that repeated cutting ofA the threads and starting of the stitching anew for each line of stitching is unnecessary, thereby insuring speedy production. i

From the foregoing description, it is believed that the nature and advantages of the present invention will be readily understood and appreciated. In Figure 1, the rolled portion of the container is shown at the left and unrolled portion at the right of the figure.

What I claim is: A container comprising a single horizontally elongated rectangular strip of paper foldedlongitudinally to provide a body portion composed of similar front and back portions and a closure flap on the upper edge of said back portion, and machine stitching including spaced parallel vertical lines of stitching connecting said front and back portions and embodying interlocked bobbin and 40 spool threads, there being a plurality of pockets in the body portion, one between each pair of adjacent vertical lines of stitching, said vertical lines of stitching extending from top to bottom of the front and back portions, said threads extending in non-interlocking relation diagonally across the front and back portions from the bottom of each vertical line of stitching to the top of the next adjacent vertical line of stitching, said threads being looped one about each other at the bottom of each vertical line of stitching, said closure flap being foldable onto saidfront portion to close the tops of the pockets.
